Patent GB-1302270-A (GB)
IPC: F16L17/02
Filed: 1970-11-05
Abstract: 1302270 Pipe couplings; joint-making packing GENERAL CONNECTORS CORP 5 Nov 1970 [7 Aug 1970] 52669/70 Headings F2B and F2G] A pipe connector comprises a tubular housing with a plurality of sealing rings retained at one end at least of the housing, one of the rings, at least, being of channel shaped cross-section. As shown in Fig. 4, the sealing rings are retained in widened bore portions 18, 48 of the connector by a channel ring insert 24. The shorter flange portion 38 of the inner sealing ring is spaced from the base 50 of the counterbore 18 and a web portion 40 of the ring is encircled by a garter spring 42. The outer sealing ring is of circular cross-section but is deformed in the retaining channel 24. Both rings bear against a pipe 14 inserted into the connector to effect a fluid-tight double seal. Vibrations and axial misalignment of the pipe and connector are accomodated by flexure of the sealing rings; the smaller flange 38 of the inner ring moving towards the walls of the housing against the influence of the spring 42. Pipes 14 are coupled to the connector externally by means of turnbuckles 66, 68, Fig. 7 mounted on flanges 56 as shown for a double ended connector in Fig. 7. Coupling bolts 76 ride in slots 72 to allow for vibrations, misalignment and thermal expansion. In a modification to the sealing ring retaining formation, a flat split washer (104) (Fig. 12, not shown) and a flange (96) integral with the housing may replace the channel ring 24. In another embodiment a connector is mounted over an opening (80) (Figs. 10, 11, not shown) in a bulkhead (78) by means of bolts and flanges (88) and a pipe is connected to the connector as before. In a further embodiment the connector and pipes may be of elliptical cross-section with correspondingly elliptical sealing rings. The channel ring 24 is replaced by a pair of L- shaped rings (112) (120) (Fig. 15, not shown) which may be welded in the housing counterbore portions. The larger flange of the inner sealing ring may be bonded to one of the L-shaped retaining rings. In order to accommodate increased flexing of the pipe connection, both seal rings may be of channel cross-section.

Title: Improvements in and relating to Data Storage Apparatus
IPC: G11C11/414
Filed: 1966-11-29
Abstract: 1,172,369. Transistor bi-stable circuit. HONEYWELL Inc. 29 Nov., 1966 [29 Dec., 1965], No. 53468/66. Heading H3T. [Also in Division G4] A bi-stable circuit suitable for a matrix store comprises two multi-emitter transistors crosscoupled between collector and base, an address selection line common to one emitter of each transistor and sense write circuits coupled to further emitters, each sense emitter being connected through a forwardly arranged diode junction to the base of a transistor and a pair of oppositely arranged diodes being connected between the sense emitter and the sense transmitter collector. Fig. 1 shows four such bi-stable circuits. The address lines X and Y are connected to the bi-stable circuits in pairs and are normally at zero voltage so that the current in the conducting transistor flows to earth through these lines. The other emitters are normally maintained at about 1À5 volts by the input circuits of the sense circuits S. Assume that transistor 4 of the bi-stable circuit L1 is conducting so that the circuit is in the " zero " state. To write a " one " in circuit R1 the appropriate X and Y address lines are raised to 3À5 volts so that the circuit current is diverted to the 1À5 volts emitter circuit 16c. A write pulse is now applied to terminal 22 of a write circuit W1 to divert the current through a resistor 88 to the emitter of transistor 86 so that transistor 100 conducts and lowers the potential of emitter 1# such that this transistor now becomes conducting and transistor 4 is switched off. In the write circuit, transistors 92 and 96 act as diodes to prevent saturation of transistor 100. Sensing is effected by circuits S. Normally, a current flows through resistor 60 (S2) and diode 50 to the base emitter junction of transistors 48 and 56 so that the sense line 34 is maintained two junction voltages positive, i.e. 1À5 volts. To sense the state of circuit R1 the appropriate X, Y address lines are raised to 3À5 volts so that the emitter current of transistor 16c, if conducting, is diverted to the base of the sense transistor 56. Previously, the collector of transistor 56 was maintained by diode 50 one junction voltage positive with respect to the sense line 44, i.e. at 2À25 volts, but the additional base current makes transistor 56 more highly conducting so that its collector voltage falls and switches over the output transistor 74. However, diode 52 becomes conducting to clamp the sense line 34 at a voltage close to its original voltage of 1À5 volts so that no appreciable change in the sense line voltage occurs during sensing. Modifications.-The sense input transistor 48 may be replaced by a diode (104, Fig. 2, not shown). In addition the bi-stable circuit transistors may have only two emitters in which case diode gating of the address circuit may be necessary. Each transistor may be replaced by a plurality of multi-emitter transistors.

A transducer for an angle-of-attack indicator for an aircraft comprises a drag responsive sensing vane 1 carried by a shaft 3 so that it adjusts itself in accordance with the wind direction, the shaft being supported by two radial gas bearings 7, 8 and an axial gas bearing 9 all externally pressurized, clamping of the movement of the shaft being effected by iron cores 21 with electrical coils 22 generating eddy currents in a bell-shaped member 20 on the shaft 3, the current in the coils 22 being varied in accordance with the speed of the aircraft. The gas bearings are fed through a connection 4 and the gas exhausts through bores 12, 13, 14 leading to the intension of the shaft 3 and then through a labyrinth 17 to the outside, the labyrinth providing a seal against dirt and moisture. In an alternative embodiment a spring-loaded diaphragm seal may be provided, this being held open by the gas pressure of the bearing and serving to seal the bearing in shutting off of the pressure. The aircraft speed is sensed by a Pilot tube (not shown) connected to a differential pressure device which serves to adjust a potentiometer connected through an amplifier to the coils 22, whereby the eddy currents produced in the member 20 are a function of aircraft speed. In this way the indicator can be used at all air speeds even supersonic speeds. The angular position of the shaft 3 is sensed by a co-operating rotor 24 and stator 25 of a synchro-mechanism.

Abstract: 1,115,588. Two or more saurees; control of electric motors. ITT INDUSTRIES Inc. 2 Dec., 1966 [6 Dec., 1965], No. 54108/66. Headings H2H and H2J. A load M such as a motor is energizable from one of two voltages through a resistor R v  which is normally shunted by a transistor T s . When the higher voltage is applied to the circuit, a Zener diode Z breaks down, rendering a transistor T T  conductive which cuts off transistor T s  hence unshunting the resistor R v . Where the applied voltage changes gradually, e.g. when fed from a battery, a sharp transistion is effected by an optional resistor R R . The switching transistor T s  may be replaced by a cascade arrangement of transistors, e.g. a Darlington pair. The arrangement may be adapted for more than two supply voltages.
